Agilent/Keysight N2755A

The Keysight N2755A is an 8-channel digital probe cable kit that adds Mixed Signal Oscilloscope (MSO) capability to select InfiniiVision Series oscilloscopes. This accessory enables simultaneous capture and analysis of digital and analog signals, making it essential for debugging complex digital circuits and integrated systems where timing relationships and signal integrity demand precise measurement. The kit connects directly to 0.1" header connectors on devices under test, delivering low-impedance acquisition through high input impedance probes that minimize loading effects on target circuitry.

Technical Specifications

• Digital Channels: 8 channels


• Input Impedance: 100 kΩ per channel


• Input Capacitance: 12 pF per channel


• Probe Loading: Low impedance connection minimizes circuit loading during measurement


• Interface: Direct connection to 0.1" header connectors on target devices

Key Features

• Two independently configured channel sets (4 channels each) accommodate measurement of pins spaced across different areas of the device under test


• Flying lead cable with integrated grabbers provides flexible point-contact probing


• Kit includes three ground extenders and three right-angle grounds for optimized ground reference connections and reduced measurement uncertainty


• Nine grabbers enable rapid, repeatable connections without soldering or permanent circuit modification


• Low input capacitance (12 pF) preserves signal fidelity in high-speed digital applications

Typical Applications

• Digital circuit debugging and timing verification


• Embedded system signal integrity analysis


• Multi-channel logic state capture synchronized with analog measurements


• Device under test characterization during development and qualification

Compatibility & Integration The N2755A integrates with InfiniiVision 2000 X-Series, 3000 X-Series, 4000 X-Series, and 6000 X-Series oscilloscopes. Earlier InfiniiVision 5000, 6000, and 7000 Series models require specific software versions for compatibility. InfiniiVision 2000 X-Series users must order the DSOX2MSO option, which bundles the N2755A cable kit with the required MSO software license.
